The 22nd annual and well-attended International Munich Paper Symposium and exhibition continued on seventh of March, with a presentation of numerous innovations and new solutions useful for pulp and paper industry.
Paper mills Trebsen and Smurfit Kappa Zuelpich presented their latest developments in dosing technology of chemical additives for board and paper production. company
After that followed several cover highlights of white water optimization in a testliner paper mill of DS Smith Packaging and a holistic approach for fixation of anionic trash in the production water in the board mill Buchmann.
Couple of successful solutions for reduction of CD shrinkage at paper mill Utzenstorf and energy savings plus process optimization through microwave consistency measurement at ProPapier were also introduces.
IMPS symposium included numerous innovations and new solutions useful for pulp and paper industry. One of these was, PermFlowDUO, felt moisture & permeability meter. It is accordint to the developer, Guiseppe Kristini, the world´s first multiple meter targeted for the press section, available on the market. It is able to detect the trend of felt moisture, water permeability and surface temperature, with great precision.
Managing Director, Ralf Pleva introduced a new robust sensor for humidity measurement. The devise called FS 91 measures at very high temperatures (up to 600°C) and high concentration of harmful vapour. According to Mr. Pleva it is extremely robust and reliable unit for measuring circulation air humidity and exhaust humidity in industrial dryers e.g.
It can be used even to measure textile, carpet, paper, wood, foodstuff, oven, building material, chemical industry and other areas. It can even control of quantity of exhaust air for energy saving and suitable for monitoring and control of humidifying units
Mr. Carda from UPM Schongau explained during the further session severeal specialties such as dynamic 3-D real-time nip impulse measurement at UPM paper mill Schongau.
Participants were also informed also about successful substitution of long fibers by short fibers with the help of Polyvinylamin at April paper mill Kerenci and a presentation of a new encapsulation technology that allows the combination starch with the desired filler material at increased paper strength.
Suction rolls used to have complex inner mechanisms; especially the sealing strips and the necessary lubrication showers have tremendous influence on the paper quality and paper machine efficiency. The preceding technology, with conventional lubrication showers, has some disadvantages where regardless how much water is used, the sealing stripes will experience a high degree of wear.
German recearchers Kosse and Honold have developed a very new sealing system to eliminate these disadvantages in paper factory Palm in Woerth at river Rhine. This innovation is the first sealing strip with integrated lubrication. The new and patented design allows lubrication only where it is needed, at the contact point between the sealing strip and the shell.
American scientists Anthony Jabar, Michael Bilodeau and Michel Muget, told the audience how encapsulation technology opens the door for game changing strength increases in paper and paperboard. By combining starch with the desired filler material, it means calcium carbonate, clay, fiber, with Ceregel A ®. The company Cerealus and The University of Maine have developed a unique solution to paper and paperboard manufacturers allowing them to increase the strength of their products.
This kind of technology gives according to Jabar the paper and paperboard maker the ability to trade that strength for a variety of economic benefits.
Reduced dependency on purchased fiber, ash increases up to 10 percent of the furnish, enhanced productivity, and improved printability to name a few of the most obvious.
Anthony Jabar and his colleagues told that this technology is used with most conventional wet end retention and drainage programs and existing equipment with minor modifications. Cerealus has raised the bar on strength development technology and consistently out-performs other dry strength programs.
The company, Deublins Sales Manager, Matthias Hameister, described this year’s IMPS-symposium as very interesting.
– Despite of the decline of global production figures for white paper we have seen a considerable increase of package paper and cardboard production, which I think depends mainly on latest boom for internet sales, said Hameister.
Obviously, he shared this judgment with many other participants that the IMPS is an excellent opportunity to discuss questions and concerns about the outlook for the European pulp and paper industry and to network with industry colleagues.
In addition to the presentations, the attendees had a possibility to visit either one of three modern German paper and board mills, or the facilities of the well-known Munich University of Applied Sciences, which offers the only English taught Master course in Paper Technology in Central-Europe.
The IMPS is organised by Professor Kleemann, and it has been held annually for 22 years. It is always focused on specific topics related to the paper manufacturing and paper supply industry. In contrast to many very large conferences, the IMPS will host about 400 participants.
Among the participants at this year’s IMPS one could meet representatives for “big players” like Metso Paper, Paper Mill Schoellershammer, Stora Enso Sachsen, Sappi Alfeld, Omya International, Hamburger Rieger, Paper Mill Utzenstorf, UPM Augsburg and DS Smith Packaging and others.
